CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202011272332.7, filed with the China National Intellectual Property Administration on Nov. 13, 2020, and entitled “IMAGE SEARCH METHOD AND COMPUTING DEVICE”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This application relates to the field of image processing technologies, and in particular, to an image search method. One or more embodiments of this application simultaneously relate to a computing device, a computer-readable storage medium, and a computer program product.

BACKGROUND

With the popularity of the Internet, people can search for any required object on the Internet, and can usually enter a name of an object or a feature of an object for search. However, features of some objects are difficult to describe in words, and therefore a user may choose to use an image of an object for search.

In the conventional technology, the user may touch a shooting button displayed by a first computing device, shoot, by using a camera of the first computing device, a to-be-searched image of a target object that needs to be searched for, and upload the to-be-searched image to a server. After receiving the to-be-searched image, the server performs similarity matching between the to-be-searched image and images in an image library, and feeds back, to the first computing device for display, a plurality of images with relatively high similarity with the to-be-searched image and files corresponding to the images as search results.

However, in the foregoing manner, the user needs to touch the shooting button to trigger an operation of obtaining the to-be-searched image, which wastes time and may reduce user experience, thereby reducing image search efficiency. In addition, the to-be-searched image may be relatively large, and the to-be-searched image may include not only the target object, but also another object. Therefore, if a search result is directly determined based on the to-be-searched image, image search accuracy may be reduced.

First, nouns related to one or more embodiments of this application are explained.

Target object: An object that a user wants to search for, for example, a garage kit or a poster.

To-be-searched image: An image including an object that the user wants to search for and that is collected by using a camera of an intelligent module. The image may be shot by using the camera when the user presses a shooting button, or may be identified by the camera itself.

Search result: An image and information that are obtained based on an object that the user wants to search for and that are related to the object.

Object detection model: A model obtained through training of a large quantity of images in which a target object exists, which may be considered as a group of model data abstracted through training. The object detection model may be configured to detect whether a target object in a model library exists in an image, and determine a coordinate group of the target object in the image.

The following describes an application scenario of an image search method provided in this application.

According to an image search method in the conventional technology, a first computing device displays a camera preview interface, and the interface displays a shooting button. A user may control a camera of the first computing device to aim at an object that the user wants to search for, and then touch the shooting button, and therefore the first computing device can shoot, by using the camera, a to-be-searched image of a target object that needs to be searched for. In this way, the user needs to perform a related operation to obtain the to-be-searched image, which causes a waste of time. In addition, after obtaining the to-be-searched image, the first computing device sends the to-be-searched image to a server. The server may determine, based on the to-be-searched image, a search result related to the target object, and send the search result to the first computing device for display. In this case, because the shot to-be-searched image may be relatively large, and if the to-be-searched image is directly sent to the server, a case of a relatively slow upload speed or even an upload failure may occur, thereby reducing image search efficiency.

To reduce a user operation and reduce duration of image search to improve image search efficiency, this application provides an image search method. A moving state of a first computing device may be monitored, and if it is determined that the moving state of the first computing device meets a preset condition, it may be considered that a user wants to perform image search, and the first computing device may be controlled to obtain a to-be-searched image including a target object; a location of the target object in the to-be-searched image is determined, and the target object is cut from the to-be-searched image based on the location, to obtain a target image; and a search result related to the target object is determined and displayed based on the target image. Therefore, the to-be-searched image can be obtained without user participation, and the to-be-searched image is cut to reduce a size of an uploaded image and increase an upload speed, thereby improving image search efficiency.

In this application, an image search method is provided, and this application simultaneously relates to a computing device and a computer-readable storage medium. Details are described one by one in the following embodiments.

FIG. 1 is a flowchart of an image search method according to an embodiment of this application. The method specifically includes the following steps.

Step 102: Monitor a moving state of a first computing device, and if it is determined that the moving state of the first computing device meets a preset condition, control the first computing device to obtain a to-be-searched image including a target object.

In this embodiment of this application, the image search method is performed by an intelligent module, and the intelligent module and the first computing device are integrally designed, that is, the intelligent module may be a module in the first computing device; or the intelligent module may be a module in another computing device, and the another computing device and the first computing device may be two different computing devices.

Specifically, the target object is an object that a user wants to search for. The to-be-searched image is an image including the object that the user wants to search for.

In actual application, the first computing device may display a camera preview interface. If a camera permission is available, a camera may be opened to enter an image acquisition page. In this case, the moving state of the first computing device may be monitored by using an acceleration sensor.

In a possible implementation, the moving state includes a moving distance, and a specific implementation of monitoring a moving state of a first computing device may include: periodically detecting a location of the first computing device within a preset duration range; determining a moving distance of the first computing device in each period included in the preset duration range based on a location of the first computing device in the period, and comparing the moving distance with a preset distance threshold; and correspondingly, a specific implementation of determining that the moving state of the first computing device meets a preset condition may include: if the moving distance of the first computing device in each period included in the preset duration range is less than the distance threshold, the moving state of the first computing device meets the preset condition.

It should be noted that both the preset duration range and the distance threshold may be set by the user according to an actual requirement, or may be set by the intelligent module by default. This is not limited in this embodiment of this application.

In actual application, if the user moves the first computing device, the acceleration sensor may sense a movement, and record a location of the first computing device. Specifically, in preset duration, the location of the first computing device may be periodically detected by using the acceleration sensor, and the moving distance of the first computing device in each period may be determined based on locations of the first computing device in two adjacent periods. The moving distance is compared with the preset distance threshold, and if the moving distance of the first computing device in each period within the preset duration range is less than the distance threshold, it indicates that a location change of the first computing device in each period is very small and may be basically ignored. Therefore, it may be considered that the moving state of the first computing device meets the preset condition.

For example, a detection period is 50 milliseconds and the preset duration range is 1 second. It is assumed that the location of the first computing device is determined once every 50 milliseconds by using the acceleration sensor, 21 locations (including an initial location) may be determined within 1 second. A moving distance of the first computing device in each period may be determined based on the 21 locations, to determine 20 moving distances. All the 20 moving distances are compared with the distance threshold, and if the 20 moving distances are all less than the distance threshold, it may be considered that the first computing device is in a relatively static state within the 1 second, and a moving range is extremely small. Therefore, it may be considered that the moving state of the first computing device meets the preset condition.

It is recorded in this application that the location of the first computing device is detected by using the acceleration sensor, and the moving distance of the first computing device is determined. In addition, when it is determined that the moving distance in each period within the preset duration range is sufficiently small, it may be considered that the first computing device is in a relatively static state, and duration is relatively long. Further, it may be considered that the user has an intention to perform image search, to determine a condition of obtaining the to-be-searched image, which does not require a user operation, and can save time.

In some embodiments, the location of the first computing device includes coordinate values in three directions, and a specific implementation of determining a moving distance of the first computing device in each period included in the preset duration range based on a location of the first computing device in the period, and comparing the moving distance with a preset distance threshold may include: determining moving distances of the first computing device in the three directions in each period based on the coordinate values of the first computing device in the three directions in each period included in the preset duration range; and comparing the moving distances of the first computing device in the three directions in each period with the distance threshold; and correspondingly, a specific implementation of determining that the moving state of the first computing device meets a preset condition may include: if the moving distances of the first computing device in the three directions in each period included in the preset duration range are all less than the distance threshold, the moving state of the first computing device meets the preset condition.

In actual application, the location of the first computing device determined by using the acceleration sensor may be coordinate values including three directions. In this case, moving distances of the first computing device in the three directions in each period may be respectively determined based on coordinates of the first computing device in the three directions in two adjacent periods. The moving distances of the first computing device in the three directions in each period are compared with the distance threshold. If the moving distances of the first computing device in the three directions in each period within the preset duration range are all less than the distance threshold, it indicates that a location change of the first computing device in each period is very small and may be basically ignored. Therefore, it may be considered that the moving state of the first computing device meets the preset condition.

For example, a detection period is 50 milliseconds and the preset duration range is 1 second. It is assumed that the location of the first computing device that includes three coordinates is determined once every 50 milliseconds by using the acceleration sensor, and 21 locations (including an initial location) may be determined within 1 second. Moving distances of the first computing device in the three directions in each period may be determined based on the 21 locations, 20 moving distances in each direction are determined, and 60 moving distances may be determined. All the 60 moving distances are compared with the distance threshold, and if the 60 moving distances are all less than the distance threshold, it may be considered that the first computing device is in a relatively static state within the 1 second, and a moving range is extremely small. Therefore, it may be considered that the moving state of the first computing device meets the preset condition.

In this way, compared with a manner of determining a moving distance based on an overall location of the first computing device, a manner of determining moving distances in more refined three directions, and determining, based on the moving distances in the three directions, whether the first computing device is in a relatively static state can more accurately determine a user intention.

Further, the monitoring a moving state of a first computing device may further include: if a moving distance of the first computing device in a first period included in the preset duration range is greater than the distance threshold, re-performing the step of periodically detecting a location of the first computing device within a preset duration range.

Specifically, the first period may be any period within the preset duration range.

In actual application, when the moving state is a moving distance, after the moving distance of the first computing device in each period is compared with the distance threshold, if it is determined that the moving distance in the first period is greater than the distance threshold, it may be considered that a location of the first computing device in the first period changes greatly, the user may substantially move a phone, and it may be considered that the user may have no intention to perform image search. Therefore, the user may return to restart to periodically detect the location of the first computing device within the preset duration range by using the acceleration sensor. In addition, an end time point of the first period may be used as a start time point of a next preset duration range.

For example, a detection period is 50 milliseconds and the preset duration range is 1 second. It is assumed that the location of the first computing device is determined once every 50 milliseconds by using the acceleration sensor, and 21 locations (including an initial location) may be determined within 1 second. A moving distance of the first computing device in each period may be determined based on the 21 locations, to determine 20 moving distances. All the 20 moving distances are compared with the distance threshold, and if a moving distance in a tenth period in the 20 moving distances is greater than the distance threshold, it may be considered that a moving range of the first computing device in the tenth period is relatively large. Therefore, it may be considered that the user has no intention to perform image search. An end time point of the tenth period may be determined as a start time point of a next preset duration range, to re-detect the location of the first computing device and perform subsequent steps.

It is recorded in this application that, if a moving distance of the first computing device in a period within the preset duration range is relatively long, it may be considered that the user may not want to perform image search, and the moving state may be re-detected in a next round. In this way, the moving state of the first computing device is continuously detected, and provided that there is a moving distance that is within the preset duration range and that is greater than the distance threshold, start time of the preset duration range is re-recorded, to more accurately determine the user intention.

Further, the monitoring a moving state of a first computing device may further include: if a moving distance of the first computing device in a first direction in a first period included in the preset duration range is greater than the distance threshold, re-performing the step of periodically detecting a location of the first computing device within a preset duration range.

The first direction may be any one of the three directions.

In actual application, when the moving state is a moving distance, after the moving distances of the first computing device in the three directions in each period are compared with the distance threshold, if it is determined that a moving distance in the first direction in the first period is greater than the distance threshold, it may be considered that a location of the first computing device in the first period changes greatly, the user may substantially move the phone, and it may be considered that the user may have no intention to perform image search. Therefore, the user may return to restart to periodically detect the location of the first computing device within the preset duration range by using the acceleration sensor. In addition, an end time point of the first period may be used as a start time point of a next preset duration range.

For example, a detection period is 50 milliseconds and the preset duration range is 1 second. It is assumed that a location of the first computing device that includes three coordinates is determined once every 50 milliseconds by using the acceleration sensor, and 21 locations (including an initial location) may be determined within 1 second. Moving distances of the first computing device in three directions in each period may be determined based on the 21 locations, 20 moving distances in each direction are determined, and 60 moving distances may be determined. All the 60 moving distances are compared with the distance threshold, and if a moving distance in an x-axis direction in a tenth period in the 60 moving distances is greater than the distance threshold, it may be considered that a moving range of the first computing device in the tenth period is relatively large. Therefore, it may be considered that the user has no intention to perform image search. An end time point of the tenth period may be determined as a start time point of a next preset duration range, to re-detect the location of the first computing device periodically and perform subsequent steps.

In this way, compared with a manner of determining a moving distance based on an overall location of the first computing device, moving distances in more refined three directions are determined, and if there is a moving distance that is greater than the distance threshold and that is in the three directions, it may be considered that the user may not want to perform image search, and the moving state may be re-detected in a next round. In this way, the moving state of the first computing device is continuously detected, and provided that there is a moving distance that is in a direction within the preset duration range and that is greater than the distance threshold, start time of the preset duration range is re-recorded, to more accurately determine the user intention.

In another possible implementation, the moving state includes a moving speed, and a specific implementation of monitoring a moving state of a first computing device may include: periodically detecting a location of the first computing device within a preset duration range; determining a moving distance of the first computing device in each period included in the preset duration range based on a location of the first computing device in the period; determining a moving speed of the first computing device in each period based on a period length of the period and the moving distance of the first computing device in the period; and comparing the moving speed with a preset speed threshold; and correspondingly, a specific implementation of determining that the moving state of the first computing device meets a preset condition may include: if the moving speed of the first computing device in each period included in the preset duration range is less than the speed threshold, the moving state of the first computing device meets the preset condition.

It should be noted that the speed threshold may be set by the user according to an actual requirement, or may be set by the intelligent module by default. This is not limited in this embodiment of this application.

In actual application, if the user moves the first computing device, the acceleration sensor may sense a movement, and record a location of the first computing device. Specifically, in preset duration, the location of the first computing device may be periodically detected by using the acceleration sensor, and the moving distance of the first computing device in each period may be determined based on locations of the first computing device in two adjacent periods, and the moving speed of the first computing device in each period may be determined based on a period length of the period. The moving speed is compared with the preset speed threshold, and if the moving speed of the first computing device in each period within the preset duration range is less than the speed threshold, it indicates that a location change of the first computing device in each period is very small and may be basically ignored. Therefore, it may be considered that the moving state of the first computing device meets the preset condition.

For example, a detection period is 50 milliseconds and the preset duration range is 1 second. It is assumed that the location of the first computing device is determined once every 50 milliseconds by using the acceleration sensor, and 21 locations (including an initial location) may be determined within 1 second. A moving distance of the first computing device in each period may be determined based on the 21 locations, to determine 20 moving distances, and a moving speed of the first computing device in each period may be determined based on a period length of the period. All the 20 moving speeds are compared with the speed threshold, and if the 20 moving speeds are all less than the speed threshold, it may be considered that the first computing device is in a relatively static state within the 1 second, and a moving range is extremely small. Therefore, it may be considered that the moving state of the first computing device meets the preset condition.

It is recorded in this application that the location of the first computing device is detected by using the acceleration sensor, and the moving distance of the first computing device is determined. Further, the moving speed is determined based on the period length, and when it is determined that a moving speed in each period within the preset duration range is sufficiently small, it may be considered that the first computing device is in a relatively static state, and duration is relatively long. Further, it may be considered that the user has an intention to perform image search, to determine a condition of obtaining the to-be-searched image, which does not require a user operation, and can save time.

Further, the monitoring a moving state of a first computing device may further include: if a moving speed of the first computing device in a first period included in the preset duration range is greater than the speed threshold, re-performing the step of periodically detecting a location of the first computing device within a preset duration range.

In actual application, when the moving state is a moving speed, after the moving speed of the first computing device in each period is compared with the speed threshold, if it is determined that the moving speed in the first period is greater than the speed threshold, it may be considered that a location of the first computing device in the first period changes greatly, the user may substantially move the phone, and it may be considered that the user may have no intention to perform image search. Therefore, the user may return to restart to periodically detect the location of the first computing device within the preset duration range by using the acceleration sensor. In addition, an end time point of the first period may be used as a start time point of a next preset duration range.

For example, a detection period is 50 milliseconds and the preset duration range is 1 second. It is assumed that the location of the first computing device is determined once every 50 milliseconds by using the acceleration sensor, and 21 locations (including an initial location) may be determined within 1 second. A moving distance of the first computing device in each period may be determined based on the 21 locations, to determine 20 moving distances, and a moving speed of the first computing device in each period is determined based on the period length, to obtain 20 moving speeds. All the 20 moving speeds are compared with the speed threshold, and if a moving speed in a tenth period in the 20 moving speeds is greater than the speed threshold, it may be considered that a moving range of the first computing device in the tenth period is relatively large. Therefore, it may be considered that the user has no intention to perform image search. An end time point of the tenth period may be determined as a start time point of a next preset duration range, to re-detect the location of the first computing device periodically and perform subsequent steps.

It is recorded in this application that if a moving speed of the first computing device in a period within the preset duration range is relatively high, it may be considered that the user may not want to perform image search, and a moving state may be re-detected in a next round. In this way, the moving state of the first computing device is continuously detected, and provided that there is a moving speed that is within the preset duration range and that is greater than the speed threshold, start time of the preset duration range is re-recorded, and the location of the first computing device is re-detected, to more accurately determine the user intention.

In actual application, when the first computing device is controlled to obtain the to-be-searched image including the target object, the first computing device may identify the target object by using a camera and obtain the to-be-searched image of the target object, so that the user does not need to manually touch a shooting button, to reduce a user operation and save time.

In this application, the moving distance or the moving speed of the first computing device may be monitored, and only when it is determined that the moving speed in each period or the moving distance in each period within the preset duration range is sufficiently small, it is considered that the first computing device may be in a relatively static state, and that the user may have an intention to perform image search. In addition, the first computing device is controlled to collect the to-be-searched image, so that the user intention can be more accurately determined, and image acquisition can be performed without a user operation, to save time and improve image acquisition efficiency.

Step 104: Determine a first coordinate group of the target object in the to-be-searched image.

In a possible implementation, a specific implementation of determining a first coordinate group of the target object in the to-be-searched image may include: inputting the to-be-searched image into an object detection model, and outputting the first coordinate group of the target object in the to-be-searched image.

The object detection model may be configured to detect whether a target object in a model library exists in an image, and determine a coordinate group of the target object in the image.

For example, the first coordinate group may include four coordinate points, that is, the first coordinate group may form a square box.

In an example, the object detection model may be pre-trained by using a large quantity of images. Specifically, a sample image may be used as a sample, and an actual coordinate group of the target object in the sample image may be used as a sample label and input into the object detection model. The object detection model may output a predictive coordinate group based on a model initial parameter, and determine a loss value based on the predictive coordinate group and the actual coordinate group. If the loss value is greater than a loss threshold, it indicates that the model has not been successfully trained, and the object detection model continues to be iteratively trained based on the loss value until the loss value is less than the loss threshold or a quantity of training times is greater than a quantity threshold. Therefore, it may be considered that the model has finished the training, and the current object detection model is determined as a trained object detection model.

In actual application, after the to-be-searched image is input into the object detection model, the object detection model may identify the target object in the to-be-searched image, and output the first coordinate group of the target object in the to-be-searched image.

For example, as shown in FIG. 2 , a dashed line box in FIG. 2 is a box formed by the first coordinate group, and coordinates of four corners of the dashed line box are four coordinates included in the first coordinate group.

In this application, a location of the target object in the to-be-searched image may be directly determined by using the object detection model, to quickly and accurately determine the target object in the to-be-searched image.

Further, before the determining a first coordinate group of the target object in the to-be-searched image, the to-be-searched image may be alternatively compressed based on a preset ratio, to obtain a compressed image.

Correspondingly, in another possible implementation, a specific implementation of determining a first coordinate group of the target object in the to-be-searched image may include: inputting the compressed image into the object detection model, and outputting a second coordinate group of the target object in the compressed image; and converting the second coordinate group into the first coordinate group based on the preset ratio.

It should be noted that the preset ratio may be set by the user according to an actual requirement, or may be set by the intelligent module by default. This is not limited in this embodiment of this application.

In actual application, the to-be-searched image may occupy relatively large storage space, that is, the to-be-searched image may be relatively large. To reduce traffic consumption and reduce a computing amount of the object detection model, the to-be-searched image may be compressed based on the preset ratio, and the compressed image may be input into the object detection model, to determine a coordinate group of the target object in the compressed image, and then the coordinate group is converted to obtain the first coordinate group of the target object in the to-be-searched image.

For example, assuming that a length of the to-be-searched image is 20 cm, a width thereof is 10 cm, and the preset ratio is 2:1, the length of the to-be-searched image may be compressed to 10 cm, and the width thereof may be compressed to 5 cm, to obtain a compressed image with a length of 10 cm and a width of 5 cm. The compressed image is input into the object detection model, to output a second coordinate group of the target object in the compressed image. It is assumed that an upper left corner of the compressed image is used as an origin, a length direction is used as an x-axis, and a width direction is used as a y-axis, and it may be determined that the second coordinate group includes four coordinates: (2.5, 1), (7.5, 1), (2.5, 4), and (7.5, 4). Further, the first coordinate group of the target object in the to-be-searched image may be determined as (5, 2), (15, 2), (5, 8), and (15, 8) based on the preset ratio.

In this application, the to-be-searched image may be compressed to determine coordinates of the target object in the compressed image, and then determine coordinates of the target object in the to-be-searched image, so that traffic consumption can be reduced, and a computing amount of the object detection model can be reduced, to improve efficiency of determining the first coordinate group.

Step 106: Obtain a target image of the target object from the to-be-searched image based on the first coordinate group.

Because the to-be-searched image may be relatively large, and the to-be-searched image may include a plurality of objects, to reduce traffic consumption and improve image search accuracy, the target object may be cut from the to-be-searched image.

In a possible implementation, a specific implementation of obtaining a target image of the target object from the to-be-searched image based on the first coordinate group may include: cutting an image that is included in the first coordinate group and that is in the to-be-searched image, to obtain the target image of the target object.

In actual application, an image in the box formed by the first coordinate group may be cut from the to-be-searched image, to obtain the target image including only the target object. For example, as shown in FIG. 2 , an image in the dashed line box in FIG. 2 is the target image of the target object. For example, the target object may be a product that the user wants to search for, and therefore the target image may also be referred to as a product image.

In this way, a size of an uploaded image is reduced, to reduce traffic consumption, and an image search difficulty is reduced, to improve image search accuracy.

In another possible implementation, a specific implementation of obtaining a target image of the target object from the to-be-searched image based on the first coordinate group may include: compressing the to-be-searched image based on a preset ratio, to obtain a compressed image; determining a second coordinate group of the target object in the compressed image based on the preset ratio and the first coordinate group; and cutting an image that is included in the second coordinate group and that is in the compressed image, to obtain the target image of the target object.

It should be noted that, in the foregoing implementation, the first coordinate group is obtained by directly inputting the to-be-searched image into the object detection model without compressing the to-be-searched image.

In actual application, because the to-be-searched image may be relatively large, the to-be-searched image may be compressed, and the first coordinate group is converted based on the preset ratio, to obtain the second coordinate group of the target object in the compressed image. An image in the box formed by the second coordinate group is cut from the compressed image, to obtain the target image including only the target object.

In this application, the to-be-searched image may be compressed and the target image is cut from the compressed image, so that a size of an uploaded image can be further reduced, and an image search difficulty can be reduced.

Further, before the obtaining a target image of the target object from the to-be-searched image based on the first coordinate group, a target probability that a target object included in a model library exists in the to-be-searched image may be alternatively determined based on the object detection model.

Correspondingly, a specific implementation of obtaining a target image of the target object from the to-be-searched image based on the first coordinate group may include: if the target probability is greater than a probability threshold, obtaining the target image of the target object from the to-be-searched image based on the first coordinate group.

Specifically, the target probability is probability that the target object is an object in the model library. Alternatively, the target probability may be understood as similarity between the target object and an object in the model library.

In an example, the object detection model may be pre-trained by using a large quantity of images. Specifically, a sample image may be used as a sample, and an actual coordinate group of the target object in the sample image and the target probability of the target object may be used as sample labels and input into the object detection model. The object detection model may output a predictive coordinate group and a predictive probability based on a model initial parameter, and determine a loss value based on the predictive coordinate group, the actual coordinate group, the predictive probability, and an actual probability. If the loss value is greater than a loss threshold, it indicates that the model has not been successfully trained, and the object detection model continues to be iteratively trained based on the loss value until the loss value is less than the loss threshold or a quantity of training times is greater than a quantity threshold. Therefore, it may be considered that the model has finished the training, and the current object detection model is determined as a trained object detection model.

In actual application, the to-be-searched image may be input into the object detection model to perform subject detection. If an output target probability is greater than the probability threshold, it may be considered that the to-be-searched image is a valid image, and the target image may be obtained from the to-be-searched image based on the first coordinate group.

In this application, before the target image is obtained, subject detection may be performed on the to-be-searched image, to determine whether the to-be-searched image is a valid image. In this way, an obtained invalid image can be identified, and then a large quantity of invalid images can be filtered out, to improve image search accuracy.

Step 108: Determine and display, based on the target image, a search result related to the target object.

Specifically, the search result may include an image, information related to the image, and the like.

In a possible implementation, a specific implementation of determining, based on the target image, a search result related to the target object may include: sending the target image to a second computing device for storage, and receiving an image address of the target image fed back by the second computing device; and sending the image address to a third computing device, and receiving the search result that is fed back by the third computing device based on the image address and that is related to the target object.

In an example, the second computing device may be considered as a server used for cloud storage of an image, and may further generate an image address of the image. The third computing device may be a service-related server, and may perform image comparison and determine a search result. The image address may be a uniform resource locator (URL) address.

In actual application, the target image may be sent to the second computing device, and the second computing device may store the target image, generate an image address of the target object based on a preset rule, and send the image address to the intelligent module. The intelligent module may send the image address to the third computing device. The third computing device may obtain the target image based on the image address, and perform similarity matching between the obtained target image and images in an image library. The third computing device determines an image whose similarity is greater than a similarity threshold as a matched image, obtains related information of the matched image, and feeds back both the matched image and the related information as search results to the intelligent module for display.

It should be noted that the similarity threshold may be set by the user according to an actual requirement, or may be set by a device by default. This is not limited in this embodiment of this application.

In an example, the second computing device may generate, based on an agreed path, a storage timestamp element, and a specific random character, an image address that can be accessed by an external network.

In an example, the related information of the matched image may be product details, a price, a purchase link, and the like of a product corresponding to the matched image.

In this application, the target image is sent to the second computing device for storage, and the image address is generated. The third computing device only needs to obtain the target image based on the image address, performs similarity matching to obtain the search result, and does not need to store the target object, which can reduce storage pressure of the third computing device.

In another possible implementation, a specific implementation of determining, based on the target image, a search result related to the target object may include: sending the target image to a third computing device, and receiving the search result that is fed back by the third computing device based on the target image and that is related to the target object.

In actual application, the target image may be sent to the third computing device, and the third computing device may store the target image, and perform similarity matching between the target image and images in an image library. The third computing device determines an image whose similarity is greater than a similarity threshold as a matched image, obtains related information of the matched image, and feeds back both the matched image and the related information as search results to the intelligent module for display.

In an example, the related information of the matched image may be product details, a price, a purchase link, and the like of a product corresponding to the matched image.

For example, FIG. 3 shows four search results.

In this application, the target image is sent to the third computing device, and the third computing device performs similarity matching between the target image and the images in the image library to obtain a search result, so that an additional second computing device is not required, to reduce interaction times between computing devices, thereby improving image search efficiency.

Further, after the determining and displaying, based on the target image, a search result related to the target object, the method may further include: receiving an adjustment operation of a user for a vertex location in the first coordinate group; re-obtaining a target image of the target object in response to the adjustment operation; and determining and displaying, based on the re-obtained target image, the search result related to the target object.

In actual application, after the search result is displayed, if the user is not satisfied with the search result, and considers that the determined target image of the target object is inaccurate, the user may manually adjust a vertex in the first coordinate group, re-cut the target object based on the adjusted first coordinate group to obtain the target image, and determine and display the search result based on the re-obtained target image.

For example, the user may manually adjust a size of the box formed by the first coordinate group. As shown in FIG. 4 , a dashed line box in FIG. 4 is a box formed by the adjusted first coordinate group, and an image in the dashed line box is the re-obtained target image. As shown in FIG. 5 , a lower part in FIG. 5 shows four search results re-determined based on the re-obtained target image.

It should be noted that a specific implementation of determining the search results based on the re-obtained target image is similar to the implementation of determining, based on the target image, the search result related to the target object. For details, refer to related descriptions in the foregoing embodiment. Details are not described again in this embodiment.

According to the image search method provided in this application, the moving state of the first computing device is monitored, and if it is determined that the moving state of the first computing device meets the preset condition, the first computing device is controlled to obtain the to-be-searched image including the target object; the first coordinate group of the target object in the to-be-searched image is determined; the target image of the target object is obtained from the to-be-searched image based on the first coordinate group; and the search result related to the target object is determined and displayed based on the target image. It is recorded in this application that, when it is considered, based on the moving state of the first computing device, that the user may have an intention to search for the target object, the first computing device may be controlled to obtain the to-be-searched image including the target object, so that a user operation is reduced, to increase a speed of obtaining the to-be-searched image, thereby improving image search efficiency and improving user experience. In addition, in this application, the target object may be cut from the to-be-searched image, to obtain the target image. Because the target image includes only the target object, the search result determined based on the target image may be more accurate, that is, image search accuracy can be improved.

With reference to FIG. 6 , the following further describes the image search method by using an example in which the image search method provided in this application is applied to similar product search. FIG. 6 is a processing flowchart of an image search method applied to similar product search according to an embodiment of this application. The method is applied to an intelligent module of a first computing device and specifically includes the following steps:

Step 602: Control the first computing device to display an image search page of installed service software.

In an implementation, a product may be searched by using the service software installed in the first computing device. The service software may be configured with an image search function.

Step 604: If the service software has a camera permission, display a camera preview interface.

Step 606: Monitor a location of the first computing device by using an acceleration sensor, and record an initial location coordinate of the first computing device.

Step 608: If the first computing device moves, the acceleration sensor obtains a first location coordinate after the first computing device moves.

Step 610: Determine moving distances of the first computing device in three directions based on the initial location coordinate and the first location coordinate.

Step 612: If the moving distances in the three directions are all less than a distance threshold, continue monitoring until the moving distances in the three directions within a preset duration range are continuously less than the distance threshold, control the first computing device to obtain a to-be-searched image, and log off the acceleration sensor.

Step 614: If at least one of the three moving distances is greater than the distance threshold, re-record start time of the preset duration range, re-determine a current location coordinate as an initial location coordinate, and return to perform step 608-step 610 until the moving distances in the three directions within the preset duration range are continuously less than the distance threshold.

Step 616: Send the to-be-searched image to a detector, and the detector determines, by using a object detection model, a first coordinate group and a target probability of a product in the to-be-searched image.

Step 618: If the target probability is greater than a probability threshold, compress the to-be-searched image to obtain a compressed image.

Step 620: Cut the location of the product from the compressed image based on the first coordinate group, to obtain a product image, and send the product image to a second computing device.

In an example, the second computing device may be a static resource server.

Step 622: The second computing device generates an image address of the product image, and sends the image address to the first computing device.

The first computing device may be a client computing device.

Step 624: The first computing device sends a product search request to a third computing device, where the product search request may include the image address.

The third computing device may be a service server that provides background service for the service software.

Step 626: The third computing device obtains the product image based on the image address, obtains a search result of a similar product based on the product image, and sends the search result to the first computing device.

Step 628: The first computing device displays the received search result.

According to the image search method provided in this application, the moving state of the first computing device is monitored, and if it is determined that the moving state of the first computing device meets the preset condition, the first computing device is controlled to obtain the to-be-searched image including the target object; the first coordinate group of the target object in the to-be-searched image is determined; the target image of the target object is obtained from the to-be-searched image based on the first coordinate group; and the search result related to the target object is determined and displayed based on the target image. It is recorded in this application that, when it is considered, based on the moving state of the first computing device, that the user may have an intention to search for the target object, the first computing device may be controlled to obtain the to-be-searched image including the target object, so that a user operation is reduced, to increase a speed of obtaining the to-be-searched image, thereby improving image search efficiency and improving user experience. In addition, in this application, the target object may be cut from the to-be-searched image, to obtain the target image. Because the target image includes only the target object, the search result determined based on the target image may be more accurate, that is, image search accuracy can be improved.
